Thread: New wrapper library: QUINCE
Hi PostgreSQLers, I've released an open-source library called quince (QUeries In C++ Expressions) that helps you access PostgreSQL from C++. I know, I know: you've got plenty of those already, but this one is different ... It's an EDSL (Embedded Domain-Specific Language), which lets you build sophisticated SQL queries in C++ syntax with C++ data types, and it's also an ORM, which figures out how to represent your C++ structs/classes/tuples as multiple columns. It's a plain old library, so no special compiler and no code generation step. And fwiw it works with sqlite too (and maybe other DBMSes in the future -- it's a matter of adding backend libraries). It's all explained at http://quince-lib.com . Cheers, --- Michael Shepanski
A cool project!

I'm not a C++ developer, but this looks like a really well-designed API. Nice work.

Sure, if that's what you're into. As the doco says:
How far you go in the direction of monster queries is up to you,
the application designer. Quince has no opinion, but whatever you
decide, quince allows you to express your choice in manageable C++.
